To all whom it may concern: swept through said passage into the passage 11 by the 55 Be it known that I, JAMES B. SCHUMAN, a citizen oi fingers 22, but, as the drum rotates, these fingers will be the United States, residing at Indianapolis, in the automatically withdrawn into the drum so that the 'county of Marion and State of Indiana, have invented smooth face ofthe drum may run very close to the edge certain new and useful Improvements in Pneumatic X, and thus prevent any straw from passing into the Stackers, of which the following is a specification, hopper, and also prevent practically the passage of air 60 The object of my invention is to produce a mechanbetween the drum and this edge into the hopper. ism for positively introducing straw or other material I deem it advisable to insure the passage of the mateinto the discharge passage of a pneumatic fan by such rial into the stream of air in passage 11 by permitting a means as will insure the passage thereof into the stream l'low of air through the hopper on top of the stream of of air, and such that there will be practically no back material. To accomplish this I provide the drums 65 pressure in the introducing hopper. with peripheral flanges 30 which preferably lie adjacent The accompanying drawings illustrate my invention: each of the teeth 22.. These flanges 30 are of less width Figure 1 is a central vertical section, and Fig. 2 a secthan the amount of projection of teeth 22 so that, as the l5 tion on line 2 2 of Fig. 1. material passes from the hopper into passage l1, it will be v In the drawings, l0 indicates any suitable blast ian held away from the surface ofthe drum thus permitting 70 having a discharge passage l1 through which a blast of an overlying stream of air to flow with the material air is forced. The passage 11 discharges into any defrom the hopper into the discharge passage l1. sirable form of delivery chute 12.
